6. Arrangement of Fuel Bed
Advice on handling and disposal
of fire ceramics
The fuel effect of the log version of this
appliance is made from Refractory Ceramic
Fibre (RCF), a material which is commonly
used for this application.
Protective clothing is not required when
handling these articles, but we recommend you
follow normal hygiene rules of not smoking,
eating or drinking in the work area and always
wash your hands before eating or drinking.
To ensure that the release of RCF fibres are
kept to a minimum, during installation and
servicing a HEPA filtered vacuum is
recommended to remove any dust
accumulated in and around the appliance
before and after working on it. When servicing
the appliance it is recommended that the
replaced items are not broken up, but are
sealed within heavy duty polythene bags and
labelled as RCF waste.
RCF waste is classed as stable, non-reactive
hazardous waste and may be disposed of at a
licensed landfill site.
Excessive exposure to these materials may
cause temporary irritation to eyes, skin and
respiratory tract; wash hands thoroughly after
handling the material.
7. Log Layout
LOGS MUST BE POSITIONED ACCORDING TO THE
